Description:

The National Geodetic Survey (NGS) has a clearly stated mission to “define, maintain and provide access to the National Spatial Reference System” (NSRS). This mission is founded in Congressional mandates and Executive orders and has been the basic mission of NGS since its inception as part of the Survey of the Coast in 1807. One critical component of the NSRS is the determination of “height”—specifically ellipsoid height, orthometric height, and dynamic height—of any point in the United States or its territories. Because NGS defines these heights in the official datums of the United States, and because all federal mapping activities are meant to be based on these datums, NGS has the critical role of proving the foundational information for all federal mapping activities in the nation.
